Hello. I recently bought this laptop that my teacher had bought from the local Wal-Mart for around $100 bucks. I thought it was a good deal, considering its worth roughly $400 on Amazon. He had it for 15 days, then somehow moved it too much and ruined the HDD (hes not too bright). Dell sent him a replacement HDD, meanwhile he bought a flash-based tablet. Now before I bought it he put in the HDD and said he powered it on and it began setting up, so he just turned it off (problem 2). Last night it ran for 11 hours on a back screen that said something along the lines of "Hard drive recognized...installing factory software...mouse and keyboard will be disabled... needs 60 minutes". 11 hrs later, i realized nothing was happening and powered it off, powered it back on, and get the Win8 lock screen after logging in to the Admin account. No Keyboard, No mouse. I can not for the life of me figure out how to enter the setup that my teacher had it in before. Any help would be greatly appreciated. Thank you!
